. PHILIP J. mx, OP BOULDER., COLORADO, ASSIGNOR OP lominiiir To Doesn E.

HOAGLAND, OF BOULDER, COLORADO.

Be it 4known 'that I, PHILIP States, residing at 'of Colorado, .have-invented certain new and useful Improvements in Tires, ofv which the following is a specification, had to tlie accompanying drawings.

This invention relates to certainv improvements in tires, land has relation more particularly to a device of this general character of a pneumatic type,

. of the invention to provide the tread portion of the tire with a novel and improved armor t whereby the possibility of the puncturing of the tire is materially reduced. t

It is also an object of the invention to providev a tire with a novel and improved internal armor,

sessesflexibility so that no interference. or

obstruction will be offered by the armor to the functioning bof the tire.

. 4The invention consists in the details of construction and in the combination and of my im'-l arrangement of the several parts proved tire Awhereby certain important ad- Y vantages are -attained and the device renview taken'throughthe tire las 'disclosed in dered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fullyset forth. The novel features .of my invention-will hereinafter-be definitely claimed.

In Order that my invention understood, I willnow proceed tov describe the same-with reference'- to the accompany-V ing drawings, wherein:- 4 i Figure 1 is a fragmentaryview 4in eleva-- tion of a portion broken away of .tire constructed in accordancewith theembodiment' of my' invention; e t

Fig. 10 illustrates another cross sectional configuration which may strands asembodiedin the forms of inven tion also particularly illustrated by Figs. 3 to .46 inclusive.

As particularly illustrated in Figs. l to vention particularly illustrated Figs. 3 tol '4 inclusive, C denotes a casing' or 'carcass of a pneumatictire of a lconventional. vtype and embedded within the tread portion thereof 'is an internal armor arranged in accordance .with an ebodirnen't-o'fmy invention.

improved armor comprises two, vseries of units in superimposedrelation with a slight series.

g55 vention; 4,- although if preferred said strand-1fL may 110 tread portion or carcass C, yet at the samev time maintains said ortion of the casing orcarcass substantial y puncture-proof. y In the embodiment ofmy invention illustrated in Fig. 5, the `units Uy are arranged vin substantially the same manner as has been set forth relative to the unit U, but the arms or portions l are disposed substantially at right angles to the longitudinal axis of each of the units or ribbons U. The units 2 are also arranged in substantially the same manner as has hereinbefore been set forth relative to the units or ribbons U,l b-ut the arms or portions 1" are substantially V- shaped in cross section with the apices extending in substantially the same direction.

In the form of my invention illustrated in Fig. 7 each of the units or ribbons R is formed of a flat thin metallic plate, preferably steel, and possessing inherent resiliency, and each ofsaid plates is provided with the slits 2 extending inwardly thereof from the opposite longitudinal margins of the ribbon or unit and in alternate relation. The

. slits 2 result in the resilient arms or portions 1c which function in substantially the same manner as has hereinbefore been particularly set forth relative t0 the arms or p0rtions 1.

' From the foregoing description, it is thought to be obvious that a tire constructed in accordance with my invention is particularly well' adapted for use by reason of the 'convenience and facili-ty with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for'this reason II do notn wish to be understood as limiting myself to the precise arrangement and formation of the Several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. An internal armor for the carcass of a pneumatic tire comprising a plurality of series of units in superimposed relation with a slight separation therebetween, the units of each series being arranged side by side, each of the units of one series overlapping adjacent units of a successive series, each unit consisting of a plurality of transversely disposed and independently movable resilient metallic arms, said units being maintained in vassembled relation wholly by the material of the casing.

2. An internal armor for the carcass of a pneumatic tire comprising a plurality of series of units in superimposed relation with aslight separation therebetween, the units of each series being arranged side by side, each of the units of one series overlapping adjacent units of a successive-series, each unit consisting of a plurality of transversely disposed and independently movable resilient metallic arms, said units being maintained in'assembled relation .Wholly by the material of the casing, each of said units `being formed of a single strand of metal returned upon itself to provide the resilient arms.

3. An internal armor for the carcass of a pneumatic tire comprising a yplurality of series of units in superimposed relation with a slight separation therebetween, the units of each series being arranged side by side, each of the units of one. series overlapping adjacent units of asuccessive series, ea/ch unit consisting of a plurality of transversely disposed and independently movable resili- `ent metallic arms, said units being maintained in assembled relation wholly by the material of the casing, the arms of each of the units being obliquely disposed.

In testimony whereof I hereunto aix my signature in the presence of ltwo witnesses. PHILIP J. MIX. Witnesses:
